Choke cable

[MattC]

Hey all,

I'm having this exact same issue with my 1450. It's both comical and annoying. Any ideas what would be causing it? My choke cable moves in and out ok. I readjusted the cable, and made sure the routing was free. Everything looks good, but somehow it keeps backing out. Is vibration causing this?

Anyone solve this issue?

When I had a choke cable that wanted to go closed as the tractor ran, this is what I found.

At some point in its life, the choke spiral outer sheath, and inner wire had been "kinked" when the choke was out.

When you pushed the choke "in", the bent wire was pushed away from the matching spot of the kinked outer sheath.

The vibration of the engine was enough to make the inner wire, and outer sheath move so that they would match again.

I happened to see the sheath move as I pushed the choke button in and out.

I bent both the sheath and inner wire back to a kinda straight condition, that stopped the "self moving choke button"...

If you can not find the problem spot, simply replace the cable assembly,
that will fix it.

Check the tension on the lever arm bolt. If the lever arm is loose the choke cable will creep. Try adding a spring washer under the lever arm.

Thanks for the advice. I'll try both and report back.

My 149 is doing the exact same thing; choke activates itself on its own as its running. Have to slap the button down every minute or two cause the engine will start running rough.

Success! I lubed up the cable, and then bent it to make it a bit harder for the cable to work it's way back. Ran the 1450 for about an hour without issue. Thanks all.
